[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides, for example Figures 1-5 The solar charge controller shown includes a body 1. Fixing plates 2 are fixedly connected to the left and right rear sides of the body 1. A display screen 3 is installed inside the upper side of the center of the front of the body 1. Multiple control buttons 4 are installed on the left, right, and lower sides of the display screen 3. Multiple wiring holes 5 are installed inside the upper sides of both ends of the body 1. Heat sink assemblies 6 are installed inside the upper and lower ends of the body 1. An adjustment chamber 7 is opened inside the lower side of the body 1, and an adjustment magnetic core 8 is installed inside the adjustment chamber 7. The body 1 is connected between the solar panel and the battery through the multiple wiring holes 5 on the upper sides of both ends and is fixed by the fixing plates 2 on both rear sides, enabling charging control. The device is connected between the solar panel and the battery. The charging controller is configured via multiple control buttons 4 and the settings are displayed on the screen 3. The charging controller can dissipate heat through the heat sinks 6 at the top and bottom of the body 1 to ensure stable internal temperature and operation. The charging controller can control the current between the solar panel and the battery through the regulating magnetic core 8 inside the regulating chamber 7 to ensure a stable current supplied by the solar panel to the battery. This prevents damage to the battery from excessive or fluctuating current, and also prevents charging efficiency from being affected by insufficient current.

[0029] Preferably, the rear end of the adjusting magnetic core 8 is fixedly connected to the inner wall of the rear end of the adjusting chamber 7. A magnetic wire group 9 is wound around the outside of the adjusting magnetic core 8. An adjusting slide tube 10 is connected to the center of the left end of the adjusting magnetic core 8. A spring limit seat 11 is slidably connected inside the adjusting magnetic core 8 and the adjusting slide tube 10. A magnetic slide rod 13 is elastically connected to the right end of the spring limit seat 11 via an adjusting spring 12. The adjusting spring 12 is located between the spring limit seat 11 and the magnetic slide rod 13. An adjusting connector 14 is fixedly connected to the right end of the magnetic slide rod 13. A connecting wire group 15 is connected to the front end of the adjusting connector 14. One end of the magnetic wire group 9 is connected to the inside of the machine body 1. A limit base 16 and a linear resistor 17 are provided at the rear end of the adjusting connector 14. The adjusting connector 14 is slidably connected inside the linear resistor 17, and the limiting base 16 is fixedly connected to the inner wall of the rear end of the adjusting chamber 7. The solar panel passes through, and the adjusting magnetic core 8 controls the magnitude of the internal magnetic force through the externally wound magnetic wire group 9. The current inside the magnetic wire group 9 is controlled by the output current of the solar panel. Since the magnetic slider 13 consists of an insulated slider on the right end and a magnetic slider on the left end, and the magnetic slider is magnetically connected to the magnetic wire group 9, when the magnetic wire group 9 is energized, the magnetic slider will slide inside the adjusting magnetic core 8 under the magnetic force of the magnetic wire group 9, and the adjusting spring 12 balances the magnetic force generated by the magnetic wire group 9. When the current inside the magnetic wire group 9 changes... During the process, the magnetic force inside the magnetic field line group 9 changes, causing a change in the force exerted by the magnetic field line group 9 on the magnetic slider of the magnetic slider rod 13. The magnetic slider rod 13 slides inside the adjusting magnetic core 8 under the action of the adjusting spring 12 to balance the change in magnetic force of the magnetic field line group 9. During this process, the magnetic slider rod 13 drives the adjusting connector 14 to slide inside the linear resistor 17, thereby changing the position of the adjusting connector 14 inside the linear resistor 17. Since the magnetic field line group 9 is connected to the input end of the solar module, and the linear resistor 17 is connected to the input end of the battery (i.e., the output end of the solar module), and the overall resistance between the adjusting connector 14 and the linear resistor 17 is proportional to the length of the linear resistor 17... Conversely, when the input current inside the magnetic field line group 9 increases, the magnetic slider 13 drives the adjustment connector 14 to slide to the left until the magnetic force generated by the current and the elastic force of the adjustment spring 12 reach a balance. This causes the connection length of the linear resistor 17 to increase, resulting in an increase in the overall resistance between the adjustment connector 14 and the linear resistor 17. This reduces the output current, which can both reduce the current input from the solar module to the battery and stabilize the input current, preventing the battery from being damaged by excessive output current or current fluctuations. When the input current inside the magnetic field line group 9 decreases, the movement of the magnetic slider 13 and the adjustment connector 14 is reversed to ensure that the output current is not too small and to ensure charging efficiency.

[0030] Preferably, the adjusting slide tube 10 has an adjusting slide groove 18 inside its front end. A limiting slide seat 19 is slidably connected inside the adjusting slide groove 18, and the limiting slide seat 19 is fixedly connected to the center of the front end of the spring limiting seat 11. A limiting slide groove 20 extends forward through the front end of the limiting slide seat 19. A limiting slide rod 22 is elastically connected inside the limiting slide groove 20 via a limiting spring 21. A limiting ring is provided at the rear end of the limiting slide rod 22, and a limiting clamp head 23 is fixedly connected to the front end of the limiting slide rod 22. A limiting clamp slot 24 is connected to the left side of the front end of the adjusting chamber 7. The limiting clamp head 23 is slidably connected inside the limiting clamp slot 24. Under the action of the limiting spring 21 and the limiting slide rod 22, the limiting clamp head 23 can tightly adhere to the inside of the limiting clamp slot 24, thus limiting the position of the limiting slide seat 19 and the spring limiting seat 11, preventing… The movement of the spring limit seat 11 affects the balance between the elastic force of the adjusting spring 12 and the magnetic force of the magnetic wire group 9. Since the limit head 23 can slide inside the limit slot 24 and the limit slide 19 can slide inside the adjusting slot 18, the limit head 23 can slide inside the limit slot 24 under the action of external force, thereby changing the position of the spring limit seat 11. Changing the position of the spring limit seat 11 while keeping the magnetic force inside the magnetic wire group 9 unchanged can change the position of the magnetic slide 13 and the adjusting connector 14 while keeping the compression length of the adjusting spring 12 unchanged. This changes the connection position between the adjusting connector 14 and the linear resistor 17, allowing the charging controller to adjust the adjustment range of current fluctuations and improve the application range of the charging controller.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
